Biological production Rate
Harvest or Removal Concept
The volume of new trees growing into measurable size during the measurement period
The volume of measurable trees dying during the measurement period
Volume of timber harvest during the measurement period
What defines an even-aged stand?
- Definite beginning and ending of a stand
- Relatively uniform diameter distribution.
- The interval between regeneration harvest = rotation
- Stand growth begins with regeneration, pre-merchantable stand, followed by merchantable volume increase over time.
What are some Even-Aged stand characteristics?
- TPA decreases over time
- Height of dominant and Co-dominant trees increase over time.
- Average DBH increases over time.
- Diameter distribution changes substantially as stand ages.
- Without intervention, mortality comprises an increasing percentage of gross increment over time.
What is MAI
Mean Annual Increment
The Slope of a straight line to the origin.
What is PAI
Periodic Annual Increment
The slope of total product curve.
What happens at the culmination of MAI and PAI?
The point where the MAI and PAI meet is typically referred to as the biological rotation age. This is the age at which the tree or stand would be harvested if the management objective is to maximize long-term yield.
What features defines an Uneven-Aged Stands structure
- No Definite beginning and end of a stand.
- Trees on a given area vary by age and size.
- Management activities are conducted via periodic treatment / partial harvests.
- Favors shade tolerant species
- The interval between partial harvest = cutting cycle
What is the silvicultural definition of Uneven-Aged Stand?
Stands in which there exist relatively large age differences between individual trees. At least three age classes present.
What is the shape of the structure curve for an Uneven-Aged Stand Structure?
What are the components of the Collection and Analysis portion of the planning process?
Inventory Resources, Analyze Resource Data, Determine Objectives, & Identify Problems.
What are the components of the Decision Support planning process?
Formulate Alternatives, Evaluate Alternatives, and Make decisions.
What are the components of the Application and Evaluation planning process?
Implement the Plan, Evaluate the Plan
What is the S in SMART Goals stand for?
Specific - Significant and unambiguous.
What is the M in SMART Goals stand for?
Measurable - Defined in quantity, space, and time.
What is the A in SMART Goals stand for?
Achievable - Realistic, agrees upon by stakeholders.
What is the R in SMART Goals stand for?
Relevant - Important for owner and society
What is the T in SMART Goals stand for?
What are Goals?
a concise statement describing the desired condition to be achieved sometime in the future. Generally, it's expressed in broad terms and is timeless.
What are objectives?
Concise time-specific statement of measurable planned results that address pre-established goals. An objective forms the basis for further planning to define the precise steps to be taken, and the resources to be used in achieving identified goals.
What is the structure for Means to Ends Analysis?
Superior goal - Attain and Education
Subordinate objective - Graduation
Sub-subordinate objectives - pass exams, study, attend lecture, pay tuition, enroll.
What is the No Stopping Rule as it pertains to Wicked Problems?
When searching for a solution, such as planning improvement, it should be a rolling process. I. e. Improvement upon improvement.
What is the One Plan as it pertains to Wicked problems?
No trial and error approach. In today's society we typically implement precautionary principles in order to avoid errors.
